Knothole Island - Part Four

You'll have to leave the island and waste some time before this second quest becomes available. Again, find the Chieftan and talk to him to accept the quest. He'll ask you first to locate the Sun Key. While he won't tell you where it is, the glowing trail will. Follow the trail just outside of town and let your dog show you where to dig up the Sun Key.

The glowing trail will now lead you to the Sun Shrine behind the village, which you can now unlock using the Sun Key. Follow the initial hall to a room with a yellow orb. Shoot the orb and then wait on the right side of the room for the orb to settle, at which point you can hit it with your sword to unlock a door on the left.

The door opens to a statue that you can activate by performing the "rude" chicken expression. The statue will then release the orb which you can shoot, knocking it to the back of the main room. Strike the orb before it returns to its original position and it'll open up a door on the right side of the room.

There's a second statue that you activate by performing the "fun" laugh expression. The orb is released once more. Hit it with a Will attack to knock the orb to the back of the main room, strike it and the orb will finally land on the left side of the room, where you can shoot it to unlock the exit.

The glowing trail leads you down another hall which drops you into a large cavern area that's crawling with beetles. Chop through the lot to unlock a door on the far side of the cavern. Through the door, follow the creek to a room with a spiked floor and an orb that seemingly runs away.
